Genesis 10:20–30 continues the genealogical record known as the Table of Nations, detailing how humanity spread and diversified after the flood. Verses 20–21 close out the descendants of Ham and then shift to Shem, underscoring him as the forefather of the Semitic peoples. From Shem’s line comes Eber, considered the root of the Hebrew identity, and Eber’s two sons: Peleg—whose name means “division,” noted because the earth was divided in his days (likely a reference to the dispersion at Babel)—and Joktan, whose many descendants populated regions of Arabia. The section describes not just individuals, but the foundations of tribes and territories, painting a picture of how nations formed and where they settled.

In essence, this passage shows the movement from one family into many peoples, setting the stage for humanity’s cultural, linguistic, and geographical diversity—while quietly steering our attention toward the line from which Israel, and later biblical history, will emerge. A family tree, yes, but one with branches that shade the whole story to come.
